（7,4）循环码的编译码器设计，模拟了信道噪声，并且进行了2种译码方法-(7,4) of the codec of the cyclic code design, simulates the channel noise, and the two kinds of decoding methods

数字信号处理，录入语音信号，加入噪声，滤去噪声，显示图形。-Digital Signal Processing

对matlab通信仿真中噪声添加进行了定量分析，分别对awgn和randn加噪进行了编程实现，对于初学者掌握matlab噪声定量添加非常有帮助。-Communication Simulation of matlab noise addition quantitative analysis, respectively awgn and randn plus noise was programming for beginners to master matlab noise dosing very

该代码的主要功能是完成加入加性高斯白噪声。(The main function of the code is to add the additive white Gaussian noise.)
